The sex chromosomes are usually XY whilst for a female they are XX for a male. A sperm has to join with an ovum (or egg cell) to make a baby.

As opposed to 46 chromosomes, therefore 23 pairs, they simply have actually 23 chromosomes as a whole. 22 autosomes and something intercourse chromosome, or allosome. An ovum will will have an X chromosome however the semen may have an X or even a Y. The gametes from the female would always be X if we looked at this in a punnett square. Therefore X, X.
